To (17] whom if may (om-mm:

Be it known that I, VTLLIAM G. ZIMMER- .n.\.\'. a citizen of the United States of America, residing at Harrisburg, in i the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Jar-Lifters, of which the following is a specification,-reference being production of a jar lifter which is formed from a blank strip of resilient wire which is folded at certain portions soas to provide spring jaws for engaging the neck of a jar in such a manner as to allow the arms thereof to easily yield when undue pressure is brought to bear thereon thereby relieving the strain from the jaws so as to allow the jaws to remain in engagement with the jar.

With these and other objects in view this invention consists .of certain novel combinations, constructions, and arrangements of parts as will-be hereinafter fully described and claimed. Inthe accompanying drawing :Figure 1 is a detailed perspective view of the jar lifter illustrating the manner in which the device is used in lifting a jar. vFi 2 is a fragmentary side elevation of the ar lifter showing the same attached to or engaging the upper portion of a jar. Fig. 3 is a fragmentary sectional view through a portion of the jar lifter illustrating the manner in which the same engages a jar and showing how the several portions will yield for supporting jars of extraordinary weight thereby relieving the strain from the jaw. Fig. 4 is a top plan view of the jaws showing the arms in section. Fig. 5 is a plan view of a portion of the blank strand of wire from which the device is formed.

Referring to the accompanying drawing by numerals it will be seen that this jar lifter is formed from a single strand of resilient wire coiled to form a spring 1 from which extend the integral diverging arms 2 and 3. These arms 2 and 3 are bent inwardly at their lower ends as indicated at 4 to provide the projections 5 extending at rightangles to the arms 2 and 3.. These prothe rib' 10.

jections are provided with the curved resilient fingers (3 extending therefrom at substantially right angles while the jaws 7 are formed integral and folded backwardly upon the fingers 6 and terminate in the lips S folded backwardly to rest upon the rear surfaces of the jaws 7 so as'to conform in contour thereto.

' \Vhen this device is in usethe spring arms will normally hold the jaws and resilient fingers in spaced relation and at a distance suflicient to allow the passing of the neck of a jar 9 to be passed therebetween so as to allow the jaws to be positioned below the annular rib 10 of the jar 9; The handles may then be compressed so as to. bring the jaws 7 into engagement with the jar 9 whereby the jaws will rest under the annir;

Y lar rib 10. By lifting upwardly the jar may be lifted to a desired position. It is part cularly desirable to use this jar lifter for lifting heated jars such as is necessary when filling thejars with a heated liquid when the contents within the jars has been cooked and it is desired to remove the jars to a desired position.

By referring particularly to Fig. 3.it will be noted that the action upon the jaws is relieved by the resilient fingers 6 when a very large jar or a \jar of extraordinary weight is being lifted. In using the device at such a time the jaws will be clamped under the annularrib 10 of the jar 9. Since this lifter is formed to provide resilient fingers 6 formed integral upon the jaws 7 when the lifter is lifted or moved upwardly so as to lift the jar, the weight of the jar will cause the resilient fingers 6 to yield slightly. The jaws however are formed integral upon these fingers 6 but will remain in engagement with the jar 9 and rest under The springing or resilient action of the fingers 6, will cause the same to yield so as to spring outwardly as disclosed in full lines in Fig. 3. This will prevent the jaws from being pulled from engagement with the rib 10 and will prevent the several portions from becoming broken as would be the case if the handles 2 and 3 were soldered or otherwise fixedly secured directly to the jaws 7. As soon as the jar is removed and the weight is relieved from the jaws the resilient fingers 6 will again spring so as to assume their normal correct position so as to allow the lifter to again engage a jar.- It will of course be seen by referring to Fig. 3

that the springing action of the resilient fingers (3 when the same yield and spring outwardly and upwardly will cause the jaws T to more firmly engage the rib 10 of the jar 9 thereby positivelyretaining the jar 9 in engagement with the lifter.

Since this litter is formed, from a single strand of resilient wire, it can be con-' structed very cheaply and will not become broken, since there are not any separable other, the weight of a jar would cause the jaws to sag at their unsupported ends and this action would make the supporting or carrying of a jar very diliicult. As the fingers and jaws are now formed, however, a jar will be held evenly without danger of falling.

From the foregoing description it will be seen that a simple and efficient jar litter has been produced which is formed from a single masses strand of resilient metal which is folded to provide springing jaws formed integral upon resilient fingers formed upon-lifting handles whereby the jaws may engage a jar and positively retain the in a position for being easily lifted when desired.

lvhat I claim is lin'a litter of the class described, formed from a single strand of resilient wire, the combination of a coiled spring, diverging arms extending tron'rsaid spring. said arms terminating in inwardly extending projections, fingers extending from said projections in opposite directions so as to be formed upon opposite sides of the vertical plane of said coiled spring, jaws formed upon said fingers, whereby said jaws will be supported at opposite ends with respect to each other, thereby allowing a jar to be gripped and held evenly, since the strain of carrying a jar will be taken up by the end portions of said fingers in alinement with each other and adjacent the central side portions of the jar.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
